yellowthunder Posted October 4, 2015 Share Posted October 4, 2015 Hi Everyone, I've been developing my open load with 115s in 38 supercomp and have a solid 169PF. The issue I'm having now is it seems like my recoil is too intense and I'm wondering how to go about "taming" that. Basically, I'm experiencing a lot of dot movement and I think that it will be too difficult to shoot quickly. Aside from improve my grip strength, or shoot it more, is there some tuning that I can do to help flatten this out a bit? Or is this part of shooting open? This is a 2011 build with a Trubor, C-More 6 MOA dot. Currently runs a 15 lb mainspring, and 13 lb recoil spring. Thanks for the help! Link to comment Share on other sites More sharing options...
echotango Posted October 4, 2015 Share Posted October 4, 2015 (edited) Try an 8# recoil spring. 13 is high. Edited October 4, 2015 by echotango Link to comment Share on other sites More sharing options...
Shadow Posted October 4, 2015 Share Posted October 4, 2015 Try 124s, not as violent as 115s for most people. Link to comment Share on other sites More sharing options...
Aircooled6racer Posted October 5, 2015 Share Posted October 5, 2015 Hello: What powder are you using? Thanks, Eric Link to comment Share on other sites More sharing options...
yellowthunder Posted October 5, 2015 Author Share Posted October 5, 2015 Shadow I'll give that a try. I had a bunch of 115s so I started there, but the next batch I'll be getting some 124s. Aircooled: Right now I'm loading 8.8 grns of Silhouette. I also have Autocomp, but I haven't worked up a load yet. Link to comment Share on other sites More sharing options...
Flatland Shooter Posted October 5, 2015 Share Posted October 5, 2015 (edited) Recoil springs. Get a variety pack from Brownells. Something between 7# to 10# should do the trick. Also some good info in the video. Edited October 5, 2015 by Flatland Shooter Link to comment Share on other sites More sharing options...

Aircooled6racer Posted October 5, 2015 Share Posted October 5, 2015 Hello: Both of those are great powders. I would try a 9lb ISMI recoil spring and see if that helps some. The 115's will have more gas to work the comp and should shoot flatter. HS-6 is another good powder as well as the more expensive N105 and N350 powders. Another thing is you may be watching the dot more than looking at the target and knowing where the dot is. Different focus than iron sights. The lighter recoil spring will help a bunch and so will shooting it more. Don't give up on the 115's just yet. Thanks, Eric Link to comment Share on other sites More sharing options...
slinginlead Posted October 5, 2015 Share Posted October 5, 2015 I like the n105 personally. I set a gun up for a friend and his gun liked 3n38 better than 105. Going to the 124's will make it a little softer on recoil and the 115's are a little snappier. Yes, going to a lighter spring will help some too. I have tried a recoil buffer and I could not really tell any difference with one and with out. Auto comp is a little faster burning and I used it to get major out of a 9mm cartridge. I have never tried it for a 38 super, I will have to look but I have a load worked up for true blue if you want to try that. Link to comment Share on other sites More sharing options...
yellowthunder Posted October 6, 2015 Author Share Posted October 6, 2015 Thanks for all the input everyone! I'll try out a lighter recoil spring and see if that helps out. My thinking was that with the 115s the comp would be working hard and the ejection would not be so violent. My friend runs a 9mm major and his loads seem to dump his brass right at his feet, so I was hoping to get something similar to happen. As for the dot movement, I'll try practicing some more with it. I am pretty used to focusing primarily on the target, but I guess I'm really relying on looking for the dot. Definitely has been different switching to an open gun from production.

Good luck, lots of dryfire will help with initially finding the dot, transitions etc. I think what your going through is minor to major PF issues. It would be more "violent" If you went production to limited or SS Edited October 6, 2015 by cnote Link to comment Share on other sites More sharing options...
BoyGlock Posted October 6, 2015 Share Posted October 6, 2015 Have a consistent grip. (Easier said than done.) Shoot a lot more with one particular load and gun set up. My tuning formula. Link to comment Share on other sites More sharing options...
bradsteimel Posted January 20, 2016 Share Posted January 20, 2016 Might try 8.7gr of N350 and a 10# recoil spring. Runs my gun and comp very nicely. Link to comment Share on other sites More sharing options...
MrRick Posted January 20, 2016 Share Posted January 20, 2016 I had the same issue with mine. It came with a 11-12# spring. Changed it to 9# and it made a nice change. I shoot 115s also. Link to comment Share on other sites More sharing options...
